The Tango E-Commerce demo is designed to give you a head start in creating production quality e-commerce solutions. Whether you are creating an online shopping solution or a business-to-business supply-chain management solution, you will hopefully find the source code for this demo useful in your development efforts.
This demo is not a production-quality online shopping solution. It was not designed as a template or off-the-shelf commerce solution. It was designed as a development aid only. Since the application files were created by experienced Tango developers, understanding the source code requires at least intermediate knowledge of programming in Tango. If your goal is to use the code from this demo to create an online shopping solution, and you are new to Tango, it is recommended that you start with the Tango tutorials before attempting to customize this demo. You may also want to take a Tango training course to supercharge the learning process. Check the Pervasive Web site for information regarding upcoming Tango training courses at a city near you.
The following describes some setup issues and a very brief overview of what each file in the commerce project is for.
This demo requires the use of Netscape Navigator or Internet Explorer 3.0 or above.
If you want automatic deletion of expired orders you'll need to create a reference to the order_deletion.taf in the crontabFile.
If you want to use e-mail notification make sure you have the address of an SMTP server in your MAILSERVER setting and that MAILSWITCH=on in your t3server.ini file.
